2 Claims. 1

This invention relates to apparatus for manufacturing electric lamps andsimilar articles and more particularly to internal ring burners used on basing or similar machines.

An object of my invention is to provide a new and improved internal ring burner.

Another object of my invention is to provide a new and improved burner to regulate, check, expand, heat, and direct a current of gas in such a manner as will bring the required amount of heated expanded gas, at a low pressure, without disturbing currents, to the position Where it becomes admixed with the requisite amount of atmospheric air for perfect combustion.

A further object of my invention is to provide a new and improved internal ring burner incorporating therewith and aspirator or breather to direct and remove by suction the burned gases from the burner without disturbing the desired expansion and form of the flame, or uniform admixture of gases and atmospheric air for perfect combustion.

Further features and advantages of my inven tion will appear from the following detailed description of species thereof.

For a better understanding of my invention reference may be had to the following description taken in connection with the accompanying drawings andits scope will be pointed out in the appended claims.

Fig. 1 is a vertical section on line I-i of Fig. 3 illustrating a five hole internal ring brazing burner incorporating my invention.

Fig. 2 illustrates a modification of the five hole internal ring brazing burner illustrated in Fig. 1.

Fig. 3- is a horizontal section of the five hole internal ring brazing burner on the line 3-3 of Fig. 1, in the direction of the arrows.

Fig. i is a section of a. modification of the burner taken on, line l4 of Fig. 5.

Fig. 5' is a horizontal section taken on line 5-5 of Fig,v 4.

Fig. 6 is vertical section taken on line 66 of Fig. '7 and illustrating a modification of the port structure of the burner shown in Fig. 4.

Fig. '7 is a horizontal section taken on line 'l 'l of Fig. 6.

Referring to Fig. 1 the live hole internal ring brazing burner therein comprises elongated cylindrical telescoped inner and outer sleeves 2 and 3, respectively, having an end of the inner sleeve 2 thereof formed as an annular surface 4 and the outer sleeve 3 having a cooperating inturned annular flange 5 provided with an annular seating surface 6 overlying and seated against the seating surface 4 on the inner sleeve 2. The seating surface 4 of the inner sleeve 2 may be provided with a plurality such as five passageways extending thereacross and communicating with the interior of the inner sleeve 2 to provide burner openings i serving as jets. The jets I are peripherally disposed, and may be positioned to produce an array of jets of peculiar configurations. For example, in the arrangement of Fig. l, the axes of the jets lie in a conical surface, and each jet axis has a substantial tangential and radial component. The inner sleeve 2 has annular ridges iii and a formed on its outer surface to provide spaced equalizer and burner manifolds l I] and E l respectively. Inner sleeve 2 provides in combination with outer sleeve 3 passageways l2 connecting manifolds It and H with each other and with the burner openings 1. The outer sleeve 3 provides a gas supply port or gas mixture inlet It for connecting a gas passageway M to manifold l0. A screen I5 is inserted in inner shell 2 to prevent back firing during operation of burner I, and a ferrule it which for example may be a skirted base of an electric lamp is inserted in the burner to indicate the relative position of ferrule to burner.

The telescoped cylinders or sleeves 2 and 3 form elongated equalizer and burner manifolds l0 and l 5 respectively. These manifolds or elongated chambers I0 and H afford sumci'ent capacity or volume while permitting a relatively small outside diameter of. the burner assembly. Suitable means may be used to seat the telescoped cylinders 2 and 3 at the end opposite the burner openings or jets.

Burner I as indicated in Figs. 4 and 5 may have, for example, telescoped inner and outer sleeves 2 and 3 respectively having an end of the inner sleeve 2 thereof formed. as an annular surface 18 and the outer sleeve 3 having an in.- turned annular flange surface HQ with at least one of the surfaces having a slit passageway extending thereacross and communicating with the interior of the inner sleeve 2 to provide a slit burner opening 20. In this manner a sheet of flame may be directed toward the center of the burner in place of live individual sources of heat as indicated in Fig. 1. Another variation of Fig. 1 as indicated in Figs. 6 and 7 may be obtained by providing the outer sleeves inturned annular flange surface 2| with a plurality of passageways extending across the annular seating surface 2| of the outer sleeve 3 and communicating with the interior of the inner sleeve 2 to provide burner openings 22, or provide seating surfaces 4 and 2| with cooperating passageways thereacross communicating with the interior of the inner sleeve 2 and together forming burner openings 22. In a similar manner outer sleeve 3 may have a plurality of annular ridges 23 formed on its inner surface to provide spaced manifolds, or both sleeves as indicated in Fig. 4 may have a plurality of annular ridges 24 and 25 formed on the outer surface of inner sleeve 2 and on the inner surface of outer sleeve 3, respectively and together provide spaced manifolds. Either sleeve, inner or outer, or both together, may provide passageways connecting manifolds l and l l with each other and the burner openings.

Fig. 2 is a view partly in section of a modification of Fig. l incorporating the above described corresponding parts of Fig. 1 with the addition of an aspirator or breather I! inserted in the exhaust end of the inner shell 2. With this arrangement, utilizing the aspirator l1, exhaust or burned gases may be by suction methods removed from the burner without disturbing the desired expansion and form of the flame, or uniform admixture of gases and atmospheric air for perfect combustion.

Fig. 3 is a horizontal section of the five hole internal brazing burner i on line 33 of Fig. 1, in the direction of the arrows formed by the telescoped ends of the inner and outer shells 2 and 3, respectively. The gas orifice or jets I are staggered around the annular flange in such a manner that a sheet of flame is directed toward the center of the burner but tangent to a circle inside the periphery of the burner.

In accordance with my invention I provide an internal ring burner Which will regulate, check, expand, heat and direct the current of gas in such a manner as will bring the required amount of heated expanded gas, at a low pressure, without disturbing currents, to the position where it becomes admixed with the requisite amount of atmospheric air for perfect combustion. Accordingly I provide an internal ring burner directly fed from a burner manifold H which checks, heats, and directs the current of gas to the nozzles or jets l of the burner. The manifold it! serves as a means of checking, equalizing and expanding the gas mixture introduced into the burner manifold H. Thus by means of the equalizer manifold l0 and the burner manifold H a stream of properly expanded pre-heated gas, at a low pressure, without disturbing currents becomes available for combustion. The inner shell 2 being hollow allows the burner flame to be directed inward and toward the exhaust end of the shell. The heat from the burned gases heats the inner shell 2 and by conduction and radiation pre-heats the gas in the equalizer manifold l3 and burner manifold I I. The aspirator or breather I? can be used as shown in Fig. 2 to aid in removal of the burned gases from the exhaust end of the burner without disturbing the desired expansion and form of the burner flame.

Generally speaking, I efiect these desired results by means of an elongated telescoped burner which provides equalizer and burner manifolds of large enough capacity to properly provide for -*the desired regulation, expansion, heating and directing of the current of gas, and to produce this gas at the jets of the burner at a low operating pressure without producing spasmodic currents.

What I claim as new and desire to secure by Letters Patent of the United States is:
